Database connection wrapper

DBCW

DBCW (Database Connection Wrapper) is a python package that allows you to connect to different types of databases and contains methods for getting the necessary data.

This is a good choice for you if you do not want to deal with queries to the database and you just need basic functionality for getting data.

But if you need to send your own query to the database - this is also possible.

Supported engines:
- PostgreSQL
- MySQL / MariaDB
